The following weighted-average assumptions were used to determine our year-end benefit obligations and net periodic postretirement benefit costs under the plans:
|  | U.S. Plans |  |  | Non-U.S. Plans |  |  |  |  |  |  |  |  |
Year-End Benefit Obligations |  | 2018 |  |  | 2017 |  |  | 2018 |  |  | 2017 |  |  |  |  |  |  |  |  |

We utilize a sensitivity analysis to measure the potential impact of changes in our healthcare cost trend rate on our Consolidated Financial Statements. Increasing or decreasing current healthcare cost trend rates by 1% would affect our accumulated postretirement benefit obligation and net postretirement expense by the following amounts for the years ended May 31, 2018 and 2017:
|  | U.S. Plans |  |  | Non-U.S. Plans |
(In thousands) |  | 2018 |  | 2017 |  |  | 2018 |  | 2017 |
1% Increase in Healthcare Cost Trend Rate |  |  |  |  |  |  |  |  |  |  |  |  |  |
Accumulated benefit obligation |  | $ | 185 |  | $ | 229 |  |  | $ | 6,978 |  | $ | 6,410 |
Postretirement cost |  |  | 7 |  |  | 9 |  |  |  | 673 |  |  | 547 |
1% Decrease in Healthcare Cost Trend Rate |  |  |  |  |  |  |  |  |  |  |  |  |  |
Accumulated benefit obligation |  | $ | (163 | ) | $ | (201 | ) |  | $ | (5,391 | ) | $ | (5,016 | )
Postretirement cost |  |  | (6 | ) |  | (8 | ) |  |  | (493 | ) |  | (406 | )
We expect to pay approximately $1.1 million to $1.5 million in estimated postretirement benefits in each of the next five years. In the five years thereafter (2024-2028) we expect to pay a cumulative total of $8.8 million.
